-LRB- CNN -RRB- -- U.N. peacekeepers and troops from the Democratic Republic of Congo are trying to bring peace to an eastern Congo town where a cattle-rustling dispute led to the deaths of 30 people .

At least 15 people were wounded in Friday 's unrest , part of ongoing violence in this area of the country , the United Nations said .

The United Nations called for an immediate end to fighting between the Bafuliru and Barundi/Banyamulenge communities in the province of South Kivu .

Martin Kobler , the chief of the U.N. peacekeeping mission in Congo , said troops would be deployed to Mutarule to assist the Congolese army and local officials .

Eastern Congo , a mineral-rich region , has been at the center of a political and ethnic conflict involving its neighbors to the east , Uganda and Rwanda , for two decades .

Government troops have also battled rebel groups such as M23 , which was defeated in November .

The persistent violence has led to thousands of families who can not farm and leave their homes for refugee camps , according to the United Nations . The international body also blames a lack of government spending on agriculture , education , health and infrastructure for the worsening situation .
